You have not lost!!!!!

Life is never gonna be easy on you.It will give you all sorts of problems.It is solely upon you ..what is it that you want?

You wanna quit...go ahead..do it...This is the best you got?...huh?...You know great men have said---"you have not lost,you have just discovered 1000 more ways that won't work".So be happy...celebrate your failure and say to life.."Is this the best you got?". Commit to yourself.I am not gonna quit.Make sure you don't repeat your mistakes.Believe in yourself. You need to be autonomous.Your mind must be free of  all the negativity.It is an acrimonious statement, isn't it?..many people will be of the view that if we wanna do something we must see all the positive and negative sides of it.blah blah...But you know what....what we all do... we all see only the negative side of every problem..what if i fail? what if this doesn't work? There lies the problem........whenever you fail ...just say..."Atleast i m done with this mistake..like forever..".

Every human being in this world is unique.He is blessed with talents.It is his job to discover them,strength them and in the process become a master of the talent itself.

"We all are awesome,

                                 We all make mistakes,

                                                                    We all can change"

You must be an aesthetic..see the beauty in every problem...have a never die attitude....And see your life turning upside Down man....Don't be a recluse.....Don't  sequester yourself from your own problems.You lose when you give up...u quit...You know our world is polarized by this statement alone.."I quit because i think i can't take it anymore".Some people are totally with it and others oppose it.The only problem with this statement is we never know that we are always one step away from answering any question,solving any problem? Just believe in the power that is vested in every human being on earth....Make mistakes...but do learn from them...But remember one thing...Don't become complacent with anything..It's like digging your own grave....You should complement your plans with the help of your confidant.Discuss with him...dig yourself up..Have collusions with him...help each other...stay positive...

If you lose and your best friend says leave it dude ..you can't do it...his complicity in this negativity will sink both your ships...so chose your friends wisely...We need to coalesce  our thoughts in the right direction...We need to form a coalition to eradicate all our negative thoughts and build on a new model of Learning by making lots and lots of mistakes..Failure is not the end of the road..but giving up..quitting is ...:)..:)..so never give up...Better make a covenant between your mind and your heart..That you will never quit...:)...

Make a goal...try to assimilate it into your life..ingest it,breath with it...Always smile away your negativity..Be charismatic...reciprocate smiles with smiles.. love with love..failure with LEARNING..and with principle of reciprocity..you can achieve anything and everything.Best of luck....for ur future endeavours...Never Give up!!!!!!!!......:)

Computer..eh?

We are often bamboozled by this question-- what is Computer ?.eh?..I have been asked this question so many times and  i replied.."hmm ... interesting question..you see my friend...."..and i m done..

Let's learn it together ..Shall we?

It is an electronic device that manipulates information or data.(Stop right there and you are done..;)).

Let's dig deeper..It has the ability to store,retrieve and process data.It consists of data as 0's and 1's and it is intelligent enough to make sense out of it.It converts these 0's and 1's into many complex things such as photograph, video....and what not.

It consists of 2 components
a)Hardware components(Physical parts)
b)Software components(Web browsers,Microsoft office tools,media player)

What Is A Server-??

They are a storehouse.They store all your files,photographs,Favourite You-tube video,audio..:).

Binary System.

A Computer understands only  1 or 0.Imagine a switch , if it is On -->1 otherwise--> 0.This system is called Binary system.0 And 1 are together termed as  bits.Computer consists of a lots of transistors(imagine a switch).Often heard of the CPU(central processing system)...It  is the brain of a computer.Hence, if your CPU is faster it means more number crunching,more switches hence faster output.It works this way--

binary-->decimal
0-->0
1-->1
10-->2(eh...?)------->(Just Chill !!!  1st digit *2^0+2nd digit*2^1+3rd digit*2^2.........go on make your own..:).....:))
11-->3
100-->4
101-->5
....................

Now let me ask you a question--->
what is the maximum number you can make with the 8 digit binary...no no i dunno wanna say...........................11111111...that would be so obvious ...:P..what is the decimal equivalent of that number..? try and scroll down for knowing the answer..;)..atleast a rough estimation mate..:)

You know how your computer accepts A,B,C..just wait ..

A->1000001(65 in decimal)
B->1000010


RAM(random access memory) is the place where your programs actually run.

The answer to the question is 255

"Computer science is fun..:)"

NS-2 Projects made Easy.

hi everyone.Are you in the search of the best places to start for your NS-2 based projects?.Welcome aboard friend...:-)

First of all what is NS-2?..eh..?

It is a sheer replica of a network.(easy)

Network Simulator is a discrete event simulator targeted at networking research.It provides substantial support for simulation of TCP(transmission control protocol)  TCP,routing,multicast protocols over wired and wireless networks.The two most important sources for learning ns-2 are 

• Marc Greis
• NS By Example.

When you start, you learn A,B,C..Z, When you simulate you begin by learning topology(mesh,star,bus).It is open and its source is freely available.More than 80% of the projects in networking research use NS-2.It is easy to interpret its result with the help of easily available tools.So Give yourself a pat,you deserve it ,you are going to learn something Amazing....Hop On!!!

The first step is to install this amazing thing.So let's get going.....
Are you a windows user..?  Gimme Cygwin!!!
Are you a linux user..?         Gimme Ns-2..:)
Still Stuck.....:-(                   Help Me!!


Basics-----

• The three most important parts are Nodes,Agents and Links.
• These nodes can further be classified with the attributes of source and sink depending on their traffic generator and/or receptor functions respectively.
• Create the Event Scheduler.
• Creating Network.
• Creating Connection
• Creating Traffic.
• Tracing.

When you run a ns-2 File (.tcl),then it will generate a trace file(.tr).This trace file will contain the information of every node at every second during the entire duration of the simulation.

  Nam is a Tcl/Tk based animation tool that is used to visualize the ns simulations and real world packet trace data .Learn More...

AWK is a programming language that is designed for processing text-based data, either in files or data streams, and was created at Bell Labs in the 1970s. . 
"AWK is a language for processing files of text. A file is treated as a sequence of records, and by default each line is a record. Each line is broken up into a sequence of fields, so we can think of the first word in a line as the first field, the second word as the second field, and so on. An AWK program is of a sequence of pattern-action statements. AWK reads the input a line at a time. A line is scanned for each pattern in the program, and for each pattern that matches, the associated action is executed." - Alfred V. Aho

The trace file is used for comparing the performance metrics of the network.It is fed as a input to the awk commands which generate the results for us.Want to learn More..Awk

Tracegraph is a third party software helps in plotting the graphs for NS2 and other networking simulation softwares. But the sad point is the software is not maintained by anyone and the happiest point is the software works fine still and it is free. 
Learn More----->Tracegraph

Best of Luck!!!!...Now you are ready to start your NS-2 research ...Have a hot cup of coffee and start exploring...:-)..
